Who are the first five people in the line of succession should Trump be unable to fulfill his duties in the role of president? Here's what you need to know about the views and values of those in line for the presidency.

1. Mike Pence, Vice President

Before becoming vice president, Republican Mike Pence served as a U.S. representative for Indiana's second congressional district from 2001 to 2003 and the state's sixth congressional district from 2003 to 2013 before being elected the governor of Indiana, a position he held from 2013 to 2017.

Republican Paul Ryan was elected to the U.S. House of Representatives in 1998 to serve Wisconsin's first congressional district and became Speaker of the House in 2015; he was also the vice presidential running mate of Mitt Romney during the 2012 presidential election. The New York Timesonce called Ryan "proudly, conservatively ideological" as well as "religiously conservative."

Hatch doesn't support same-sex marriage, though he reportedly advocated for same-sex civil unions with similar rights to those in traditional marriage. He opposed Trump's initial Muslim ban, specifically critiquing how many people who weren't threats to the country would have problems receiving visas under Trump's order. He considers himself a strong advocate of religious freedom, and he once wrote that Democratic presidential nominee Hillary Clinton was "no friend of religious liberty."

Despite later voicing support for Trump's second executive order calling for a Muslim ban, Tillerson [spoke out against Trump's Muslim ban] during his Senate confirmation hearing earlier in the year. According to NPR, he said that he did "not support a blanket-type rejection of any particular group of people." During his hearing, he also said that climate change was real.

5. Steven Mnuchin, Secretary of the Treasury

Like Tillerson, Steven Mnuchin had never served in public office before being confirmed as secretary of the Treasury in 2017. His past experiences involve working for Goldman Sachs and other banking positions and even testing out the waters in Hollywood. He faced scrutiny during his Senate confirmation hearing due to his status as a banker and hedge fund manager during the recession that hit in the late 2000s.

During an interview with CNBC back in November 2016, Mnuchin said his primary concerns if confirmed to the position would be increasing wages and making sure American workers have "good jobs." In February, he remarked that he wanted to see "very significant" tax reforms by August, according to Fortune. However, Bloombergreported that hiring for Mnuchin's department had stalled due to questions about several picks' loyalty to Trump, so it might take longer than expected to see where Mnuchin stands on larger monetary issues as well as which policies he implements.
